Hello Guest!
Welcome to the official Square Foot Gardening Forum.
There's lots to learn here by reading as a guest. However, if you become a member (it's free, ad free and spam-free) you'll have access to our large vermiculite databases, our seed exchange spreadsheets, Mel's Mix calculator, and many more members' pictures in the Gallery. Enjoy.

your garden looks great! I use the same types of covers you do, and love them! did you make them yourself? What type of frame do you have on the bottom if any? Looks like wood or metal? Congrats on a nice garden...
